SKNPC Series Stainless Steel Male Connectors

Features & Key Specifications

Secure Quick Screw Connection:

Simply push the tube onto the barb and tighten the external nut for a vibration-proof and highly secure connection, rated for working pressures up to 3.0 MPa (30 bar).

Extreme Temperature & Pressure Range:

Engineered to perform in the most demanding conditions, this high-pressure, high-temperature fitting is suitable for everything from cryogenic applications to high-temperature steam lines.

Superior 316L Stainless Steel:

The use of 316L stainless steel provides maximum resistance to corrosion from aggressive liquids, steam, and harsh cleaning agents.

Versatile Media Compatibility:

Designed for use with not just air, but also water, steam, and other corrosive liquids, making it a true industrial-grade process fitting.

Comprehensive Size & Thread Options:

Tube OD (Metric): 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm

Port Sizes: M5, 1/8", 1/4", 3/8", 1/2", 3/4" in NPT, BSPP (G), and BSPT (P) threads.

Application Fields

The Secure Connection for Demanding Systems:

High-Pressure Pneumatics: Ideal for systems operating above the standard 1.0 MPa.

High-Temperature Process Lines: Used in applications involving steam, hot water, or in high-temperature environments.

Food & Beverage Washdown: A robust fitting that withstands frequent cleaning with harsh chemicals.

Chemical Transfer Lines: Providing secure connections for tubing that handles corrosive liquids.

Technical & Selection Guide

Why Choose a Quick Screw Fitting?

A quick screw fitting offers a higher level of security than a standard push-in fitting.

Higher Pull-Out Resistance: The nut-tightened design provides a much stronger grip on the tube, making it ideal for applications with high pressure, pressure spikes, or mechanical pulling forces on the tube.

Vibration Resistance: The secure connection is highly resistant to loosening caused by machine vibration.

FAQ

Frequently Asked questions

Q: What type of tubing is this fitting for?

A: It is designed for use with semi-rigid polyurethane (PU) and nylon tubing.

Q: Is this fitting reusable?

A: Yes. You can loosen the nut, remove the tube, and reconnect it multiple times.

Q: Can this handle 300°C temperature?

A: The 316L stainless steel body can withstand 300°C. However, you must use a tube material (like PFA or metal) that is also rated for that temperature. The overall system's temperature rating is limited by its weakest component.
